Abstract

Since major driving forces of vertical mixing processes are wind and wind wave mixing, the boundary condition of turbulent kinetic energy flux at the ocean face is formulated as cubic of friction velocity by Craig-Banner relation. It is not well verified in general conditions including wave conditions and shallow water environment. This study estimates effects of wave conditions on vertical mixing processes at the ocean upper layers in the stormy condition. The field observation was conducted during typhoon Melor in 2009. The observed water temperature distributions indicate importance of wind and wave induced mixing in the nearshore. The numerical results show that the wave induced vertical turbulent flux significantly influences on the water temperature and the current, respectively.
